With regards to building a bolt action .223 Rem. LTR and using factory match (63 -69gr.)ammo; what is the shortest barrel length one can use before seeing a drop in velocity?

I see alot of target type rifles with 20" barrels but would like to hear what you have proven to be true.

Thank you,

Sam

Jump over to the reloading pages and take a look under .223. A 223 barrel was cut down a inch at a time, results are posted.
